PERMANENT TRANSFER. BINDER.

Application filed October 27; 1921. Serial No. 510,871.

T 0 all whom it may concern:

Be it known that l, Gnonen VJ. NEWMAN,,

a citizen of the United States, and a resident of the city of Chicago inthe county of Cool: and State of Illinois, have invented certain new anduseful Improvements in a Permanent Transfer Binder; and I do herebydeclare that the following is a full, clear, and'exact description ofthe same, reference being had to the accompanying drawings, and to thenumerals of reference marked thereon, which form a part oft-hisspecification.

This invention relates to atransfer binder for loose leaves in which theleaves are permanently clamped against removal.

It is an object'of the invention to provide friction producingmeans forinterlockingly clamping a pair of relatively. slidable smooth leafholding posts.

It is a further objectof this invention to provide a tiltable clamp forfrictionally interlocking a set of leaf holding posts it is a furtherobject of this invention to provide a tiltable friction producing meansfor aset of leaf holding posts that is auto niatically tilted intooperative engagement with said posts during the assembling operation.

It is afurther object of this invention to provide a clamping'means for.a'set of leaf'holding posts that allows free relative sliding movementof said posts until the leaves properly compressed.

It is a further object of this invention to provide means forfrictionally clamping a set of leafholdi-ng posts by compressing thebinder; p With these and other objects in view, which will become moreapparent in the following description and disclosures, this inventioncomprises the novel features of construction and combinationshereinafter described and more particularly pointed out and defined inthe appended claims In the drawings, which illustrate a preferredembodiment of my inventionand in which similar reference numerals referto similar features in the different views:

Figure 1 is a perspective view of a binder containing the constructioninvolving my invention.

Figure 2 is a section on the line 22 of Figure l.

with the. interlocking construction, having Figure 3 isan enlargedplaniv iew'o f the interlocking means for a set of leaf holding postsshown in section.

Figure 4 is an elevational view 'of a set of be noted thatI haveillustrated in Figure meansin operative" po- 1, pair of covers 1 ofsuitable material and clamped between these covers by my novelmechanism. I I r f In the illustrated embodiment of. my invention two.sets of leaf holding used. The individualpos ts ofea'e-h set mayconsistof smooth flat members2 and 3 which can be readily stamped fromsheet metal or the like and provided with proper."heads 4. I preferablymake oneof the members such width than the member 3. andcurve itsimpaling endslightly outwardly with respect to the other member. Thesefeatures aid greatly in assembling the binder. f V

Each set of posts is so supported by the covers that the individualmembers'of each set are brought into substantial slidable abuttingrelation when the binder is assembled, and in order to permanently clamp1 each set of posts when a stack of'leaves has er ably' consists of aslightly [resilient flat suitable hinge joints.- Loose leaves areadapted to he permm ently posts are 7 been properly compressedbetweenisaid covmetal strip-having a slot near its ccnt'ral--" portion.A pair of opposite walls of said slot-have reverselydeflected resilienttongues 6 and T struc'l: therefrom which exercise a clamping action uponthe posts 2 and 3 that are adapted to p'ass through the slot. It will benoted'that one portion of the slot-is wider than the other portionformingthereby a pair of shoulders. 8 against which the binder post 2 isadapted to abut, so that a ready space will be left for the insertion ofthe post 3 thereafter.

The clamping members 5 are adapted to V be embedded 'at suitable depthsbetween the leaves so that the individual leaf holding posts of e ch Setmay pass therethrough.

Thus leaves may be impaled upon the posts 2, and after a suiiicientquantity has been thuswise impaled, and before the top of said posts areburied as shown in Figure 2, the clamping members 5 may be slipped overthe posts 2. Leaves may then be further impaled upon the posts 2and'stacked above the clamping members 5 to any desired height, whichhowever should not extend to such a height as to prevent the posts 2from entering the slots in the clamping members for proper clampingaction therein. If desirable, a sufiicient stack of leaves may beseparately impaled upon the posts 2 and 3 to form two distinct halves.The clamping members may then be slipped over the posts 2 and the otherhalf of the impaled leaves superimposed thereon with the posts'3entering the slots in the clamping members. In either method ofimpalin-g,

the clamping members 5- will have an oblique or tilting position withrespect to the posts, allowing relative sliding movement of theindividual posts of each set. Therefore, when the covers of the binderare pressed together to compress the leaves, the posts 2 and 3 willslide relatively to each other for this purpose. However, when theleaves have become tightly compressed, the

pressure will have caused the tilting clamping members 5 to assumesubstantially horizontal positions as shown in Figure 5, or

at right angles to'the posts, in which positions thetongues 6 and 7 willpress against the sides of the posts of each set to friction ally clampthe posts of each set together. It should be noted that the tongues '6and 7 are so directed that any force tending to expand the binder orseparate the covers will increase the clamping action or frictionbetween the respective post of each set.

It will accordingly be apparent that I have devised a clamping memberthat cooperates with the leaf holding posts in, such a way that relativeslidable movement of the posts is permitted for firmly compressing theleaves of the binder, and wherein a strong frictional clamping action ofthe posts is attained when proper compression of the leaves occurs, andwhich frictional clampby compression of the leaves of the binder:

for frictionally clamping each set of posts together.

In a transfer binder, a set of relatively slidable and smoothimpaling posts adapted for securing the leaves of the binder, and aclamping member therefor having an aperture with reversely directedresilient tongues for receiving said posts when in inclined position,said member being adapted to be embedded in the leaves of the, binder,and straightened to horizontal position by compression of the leaves forfrictionally clamping said posts together.

6. The combination in a binder for sheets perforated to receive bin-dingposts, binding bars, post members arranged on said binding bars incoacting pairs for slidable engagement within the sheet body, and aclamping means adapted to be disposed between sheets of the sheet bodyand actuated by the pressure of the sheets thereon to clamprthe postmembers together.
